After all the anger and disbelief at Carlos Tevez's behaviour in Munich it was on Friday night reported that one of Roberto Mancini's sons, Filippo, had done exactly the same thing as the Argentinian six weeks ago.

Filippo, 20, reportedly refused to come on as a substitute during an Elite Development Squad match against Liverpool on 10 August. When asked by Andy Welsh, the manager of Manchester City's Elite Development Squad to replace another player after 80 minutes of the match, Filippo would not go on and is alleged to have exchanged angry words with Welsh before storming off.

Mancini's other son, Andrea, also started the match on the bench but came on in the 60th minute.

Fillipo, who played for Virtus Entella last season in the Lega Pro Seconde Divisione, Italian football's fourth division, was using the pre-season friendly, played at Hyde United's Ewen Fields Ground, to gain match fitness.

No disciplinary action was taken against the player as he is not contracted to Manchester City.

"Filippo is a non-contracted, unpaid player who was on the bench for a non-competitive game," a club spokesman said. "In these circumstances a disciplinary procedure would have been invoked. However, as he was not an employee of the club, this was not a viable option."
